WIRE-'COILING APPARATUS.

Specification of Letters Patent.

Patented Mar. 22, 1910.

Application -iled February 19, 1909. Serial No. 478,850.

To all whom it may concern.:

Be it known that I, CHARLES L. RITTER, a citizen of the United States, residing at Norristown, in the county of Montgomery and State of Pennsylvania, have invented new and useful Improvements in `Wire Coiling Apparatus, of which the following is a specification.

This invention relates to. wire coiling apparatus, and has for an object` to provide apparatus -of this character that will be provided with means so that a single length Iof wire can be conveniently and accurately coiled to form a coil spring or a coil for any desired purpose, and to further provide means in the format-ion of the coil for arranging its-convolutions at their proper distance from each other to increase or decrease the strength of a spring.

A further object of my invention resides in the peculiar lconstruction of a support provided with means for revolubly mounting crank rods of different diameter for forming coils of various sizes.

A further object of my invention resides in the eculiar construction of Wire guide disposed directly' above the crank rod, and aims -to 'provide -simple and elfective means to be used in connection with the :guide for regulating the desired tension against the wire to be coiled.

Other objects and advantages will be apiparent as the nature of the invention is betterset forth, and it. Will be understood that changes within the scope of the claims may be resorted to without departing from the spirit of the invention.

'In the drawings, forming a portion of this' specification and in which like numerals of reference indicate similar parts in the several viewsz-Fgure 1 is a front View of the coiling apparatus. Fig. 2 is a vertical section taken through the same. Fig. 3 is an end view. Fi 4 is a detail horizontal section taken. on t e line 4-4 of Fig. 1. Fig. 5 is a detail front elevation of a portion of the apparatus showing the manner of forming a coil in which its convolutions are closely assembled. Fig. 6 is a detail view of the gage nut. Flg. 7 is an end view of the gage nut.

Referring now more particularly to the drawings, there is shown a wire coiling apparatus embodying a base or bed plate 1 provided adjacent to its ends with bolt receiving passages 2 so that the said plate can be securely anchored upon a work table or bench. The formation of the base or bed plate 1 need not be limited to the formation therein of the passages 2, this being an obvious construction as it will be appreciated that the said base or bed plate can be provided with any suitable anchoring or Vet-aining means for holding it in its operative position. The base or bed plate has extending therefrom vertically disposed standards or supports 3 and 4 located in spaced relation to each other, and as shown, each standard or support is provided with a vertical series of differently sized passages 5, the passages in the standard 3 being arranged yin alinement with the passages in the standard 4 as shown in Fig. 2 of the drawings.

As stated, the passages 5 formed in the standards or supports 3 and 4 are of different sizes, so that a rod or coiling Aelement lidentical in construction to the one shown at G'can be effectively and conveniently journaled in a pair of said passages. The rod or coil element `6 is provided at one end with an elongated slot 7, and at the other end the rod or element is `provided with a crank portion 8 so that the element or rod can be manually revolved. The standard or support 4 has slidably mounted thereon Ia block or vguideeIement '9. provided with a threaded stud 10 located directly above the rod or coiling element G and in spaced parallel relation thereto. The block or guide element 9 has extending therefrom at the top a plate 11 in which is formed a passage 12 disposed in line with a passage 13 formed in the stud 10. A washer 14 is removably mounted upon the stud 10, and a gage nut or member is mounted upon the stud 10 ontwardly of the washer 14 and is spaced therefrom, as shown. The nut or member 15 is providedwith a series of radial wings 1G each of which is of a different diameter for a purpose to be hereinafter described. A clamping nut- 18 is engaged with the stud l0 and is adapted to be frictionally engaged with the face 17 of the member or gage nut 15. In order that the block or guide element 9 can be held in its adjusted position upon the standard or support 4 I provide said block or element with a clamping bolt 19 adapted to be engaged-With the standard or support 4 as clearly shown.

The construction of the apparatus is such that the` rod or coiling element 6 is revolubly and slidably mounted in the standards or supports 3 and 4, and in operation when it is desired to form a coil the rod or element G is moved so that the slot 7 Jformed atone end thereof is disposed in vertical alinement with the passages 12 and 13 formed in, the stud 10 and in the plate 11 upon the guide element or block 9. After the guide block or element 9 has been properly adjusted upon the support or standard 4 a strand or single length of wire A to be coiled is inserted at one end in the passages 12 and 13 and the terminal end of the wire is passed through the slot 7 after which the rod or element G can be revolved to form the first convolution of a coil. After the first convolution has been formed the gage nut 15 tan be properly positioned so that one of the radial wings 16 extends downwardly toward the rod or element 6, and upon revolving said rod or element it will be seen that the wire A will be eectively coiled upon the element with its convolutlons in spaced relation to each other as shown in Figs. 1, Q and 4 of the drawings. Should it be desired to form a coil without spaces between its convolutions the guide block or element i) is moved upwardly upon the standard 4 so as to move the wings 16 into an inoperative position. In forming a coil it will of course be understood that the rod or element 6 is moved longitudinally through the standards 8 and 4 so that the wire can be accurately wrapped or wound with its convolutions properly positioned fromv each other. While I preferably employ a slot .7 at one end of the rod or element 6 it will of course be understood that any other obvious means can be employed for retaining one end of the wire to said rod or element. After the wire has been properly formed into the desired coil the coil may be `'slipped' spaced standards, a revoluble coil forming element mounted for horizontal sliding movement in said standards, a vertically adjustable wire guiding element mounted upon one of the standards and movable toward and away from the said wire coiling element, and a gage removably mounted upon the guiding element and provided with means or spacing the windings of a wire from each other.

3. Apparatus of the class described, comprising standards, a removable coil forming element mounted in the standards for horizontal sliding movement, a wire guiding element mounted upon one of the standards, a threaded stud carried by the guiding element, a gage revolubly mounted upon the stud, and means for clamping the gage upon the stud to hold the same against rotation.y

In testimony whereof I aix my signature in presence of two witnesses.
